His men's health book, Improving Male Sexuality, Fertility and Testosterone, was #1 in the Amazon Health Sex section for more than a week and his breast cancer book, The Breast Cancer Patient's Survival Guide: Amazing Strategies for Winning, was #1 in the Amazon Health Reference section. He is also an entertaining and dynamic educator and speaker (he has never NOT been voted as The Most Popular Speaker at any conference at which he's spoken) and is popular among both the public and physicians, and has travelled many thousands of miles doing book, radio and product tours all over the world.

He is also the founder of a couple of successful health product design companies through which he makes a number of products for nutraceutical companies. He is also a BIG fan of Disneyland and Disney World where you can probably find him in his off time with his wife and some of their 10 children.
